Wild new Specialised Diverge suspends the rider with absolutely damped rear Future Shock


The 2023 Specialised Diverge STR gravel bike provides a singular rear Future Shock seat tube with a hydraulic high tube movement damper to manage the flex. Mixed with their steer tube Future Shock up entrance, the bike retains the rider floating over chatter for a smoother, sooner journey.

The design is wild, leveraging nearly the complete size of the seat tube (not seat put up, however seat tube) to supply flex, giving it lots of journey. Right here’s every little thing it’s essential to know in regards to the new Diverge…

What’s new? What’s the identical?

The Specialised Diverge STR will sit on the high of their gravel bike lineup alongside the Crux S-Works, simply with a really completely different rider in thoughts. The Crux will stay their lightest, race-focused bike, however the Diverge STR will doubtless be the bike of selection for his or her execs on rougher programs.

The usual Diverge design, with out the rear Future Shock, will stay within the lineup, too. Actually, the brand new STR mannequin shares the just about the identical geometry, with just a few refined tweaks:

  • Stack & Attain are equivalent
  • STR BB drop is 85mm, 5mm greater than commonplace
  • Chainstay size is 429mm, 4mm longer than commonplace
  • Seat tube angle is 0.5º steeper, however…

…the marginally steeper seat angle is offset when you sit on it and the system is sagged, making the efficient seat angle the identical as the usual Diverge as soon as your weight is on it. Specialised suggests sliding your saddle 5-10mm extra ahead to account for the sagged flex, placing you in the identical place as on a totally inflexible bike.

Tire clearance is 700×47 (or 650Bx2.1″), and downtube SWAT storage comes commonplace with included device baggage (fill it with no matter you need, or stuff a rain jacket in there).

How a lot does the Diverge STR weigh?

An S-Works Diverge STR body weight is simply 1,100g (claimed, FACT 11R body, measurement 56, painted with no {hardware}, and with out damper…hold studying), about 100g greater than a typical S-Works Diverge body.

And it’s a “inflexible” body, which was the purpose. Specialised needed to maximise energy switch and general effectivity, so the bike handles like a traditional inflexible bike. Get up and the rear Future Shock does nothing, turning your legs and arms into the suspension. Fortunately the entrance Future Shock nonetheless delivers its 20mm of journey, standing or sitting.

All in with the complete rear Future Shock system, an STR body will weigh nearly 400g greater than a typical body, however that features the headset, SWAT system, and {hardware}.

An entire 56cm S-Works Diverge STR weights 8.5kg (18.75lb) setup tubeless, out of the field. A Professional mannequin weighs 8.9kg (19.6lb), and an Skilled mannequin weighs 9.5kg (20.9lb).

How does the Diverge STR rear Future Shock work?

To be clear, this isn’t a “full suspension” bike within the conventional sense. The aim is to droop the rider to allow them to stay seated, comfortably, and energy by means of chunky programs with out losing vitality hovering over the saddle or bouncing round.

Specialised has been engaged on how to do that since at the least 2017. Current variations of the Roubaix and commonplace Diverge dropped the seatpost clamp decrease to offer the seatpost extra room to flex. That was wonderful for endurance street bikes, the place you could race on cobbles often. However gravel bikes had been taking over ever more difficult terrain.

Clockwise from high left within the picture above are prototypes beginning with an eccentric backside bracket that allowed an internal shaft to maneuver inline with the seat tube. From there, they moved to a vertically suspended seatpost with a rear air shock related to the underside bracket, retaining efficient saddle peak unchanged even because the rider “felt some suspension.

Each of these early designs worked-ish, however could be far too sophisticated to fabricate at scale. Finally, they moved to the prolonged versatile seatpost idea, which was less complicated and supplied the specified advantages whereas maximizing stiffness and minimizing weight.

The rear Future Shock offers as much as 30mm of journey through the use of what’s successfully a very lengthy seat put up anchored very low within the body that’s unattached to the highest tube or seat stays.

There are, truly, two seat tubes on the body. The exterior one you see, and a separate inner carbon-and-glass fiber tube that bolts into the body simply above the underside bracket. That attachment level acts because the pivot, permitting the complete tube, and the seatpost inserted into it, to behave like a leaf spring.

The exterior seat tube is ovalized close to its high, creating room for the inner tube to flex rearward.

Specialised will supply 9 completely different seat tubes, and every of these has two distinct flex traits due to completely different layups and materials combos, offering 18 whole “tunes” to work for nearly any rider weight.

Every bike will include two tubes overlaying the anticipated vary of rider weights for that body measurement, in whole overlaying riders from 110lbs to 275lbs. (The bike has a complete rider+cargo weight restrict of 275lbs)

Right here’s the catch: A very lengthy carbon leaf spring may flex rather a lot, after which rebound fairly forcefully, bucking the rider. So it wanted to be managed, and that’s the place the hydraulic damper is available in.

Primarily the identical because the damping circuit present in a suspension fork or shock, the STR damper has separate compression and rebound circuits.

The compression (which, on this case handles the extension of the “shock”) has a 3 place adjustment – open, medium, and agency. This controls the movement, stopping it from catapulting you ahead on each rebound, and eliminating any “bobbing” that would happen from an undamped system.

The rebound is adjustable with a hex wrench by means of a port underneath the highest tube, making the system absolutely adjustable.

How do I regulate the Future Shock seat tube suspension?

Every inner put up has two efficient layups, with a clocking groove that retains it aligned. Merely rotate it 90º to modify the stiffness. The posts are clearly marked with numbers.

The upper the quantity, the stiffer the put up, and it’s a linear development. That means, a put up marked “60” is twice as stiff as a put up marked “30”. Or, a 30 put up will flex twice as a lot as a 60 put up.

The numbers point out their flex as measured in N/mm, which, actually, means nothing when it comes to which put up you need to select…however, you understand, enjoyable truth?

Specialised says the 2 posts included with every bike ought to make most riders blissful, giving them 4 distinct choices. In addition they say most riders can inform a noticeable distinction with a ten% change (ex. going from a 40 to a 44 put up), and {that a} 20% change is very noticeable. Mix these with the three compression damping settings and it makes it simple to wonderful tune for anybody’s choice.

The damper connects to the put up with an alloy “tendon”, and it has a wrench faces to carry it degree when unbolting it so that you just don’t bend and harm it when swapping posts.

However you solely must loosen it to swap inner posts; your precise seatpost could be adjusted and eliminated like regular. And it makes use of a traditional 27.2 seatpost, so you should use any put up you want, even switching to an alloy put up if you wish to scale back general flex.

What about body baggage, racks & fenders?

The fork has three mounts, letting you run accent cages or a lowrider rack, and fender mounts. The rear, although, has no mounts for both rack or fender.

Prime tube bag mounts come commonplace, and strap-on body baggage can be utilized so long as they don’t intrude with the damper or rub the rubber boot across the seat tube. Saddle packs and baggage can be utilized like regular, but when it’s heavy you could need to use a stiffer put up.

2023 Specialised Diverge STR costs & choices

All fashions use a threaded backside bracket, flat mount brakes and through axles with full inner routing…for brake hoses and wires, it’s designed just for digital shifting teams. You’ll discover solely SRAM builds right here, nonetheless you need to nonetheless be capable to construct a motorbike with Shimano Di2 because the internal seat tube is hole and would permit the battery wires to move by means of to the seatpost battery.

An S-Works frameset ($6,000), together with fork with Future Shock steerer is out there if you happen to’d love to do simply that. A small wire entry port sits underneath the rear brake hose entry on the head tube, and there’s an exit port simply above the rear dropout.

As for dropper seatposts, there aren’t any mechanical routing choices, however you possibly can set up a Reverb AXS put up. The body is 1x solely, so that you received’t be giving up entrance derailleur compatibility so as to add the wi-fi dropper.

All bikes get Supacaz Tremendous Sticky Kush handlebar tape, which is superior.
